Belkin Residential Gateway (RG) Battery Backup Revision B

Battery backups provide an uninterruptible power supply (UPS) to keep critical systems up and running in the event of a power loss. 

The Belkin Residential Gateway (RG) Battery Backup REV B, BU3DC001-12V has been designed to maintain your AT&T U-verse Residential Gateway and your AT&T U-verse Voice service should a short disruption to your commercial power service occurs.

System Requirements

The RG Battery Backup is designed for use with the AT&T U-verse Residential
Gateway and your AT&T U-verse Voice service.
NOTE: Your AT&T U-verse Voice service, including 911 dialing, will not function
without electrical or battery-backup power. The RG Battery Backup supplies
power for your AT&T U-verse Voice service; it does not supply power for
cordless phones (and it does not supply power for your network interface
device or optical network terminal, typically located on the outside
of your home, which may also require battery-backup power for your
AT&T U-verse Voice service to function).
Therefore, in the event of a power outage, you should ensure you have one
corded single-line, touchtone phone connected directly to the AT&T U-verse
Residential Gateway or your in-home wiring and the AT&T U-verse
Residential Gateway connected to the RG Battery Backup. (Rotary/pulse phones
do not work with AT&T U-verse Voice service.) If you connect more than one
corded phone, it will use more power; if you connect a cordless phone,
it will not function without a separate battery backup, and not all cordless
phones are so equipped. If you have a monitored home alarm, you should
never plug a multi-line phone directly into the Residential Gatewayit could
interfere with the alarm signals. You should not connect the RG Battery Backup
to any device other than the AT&T U-verse Residential Gateway or use it with
any service other than your AT&T U-verse Voice service, and you should
always have an alternative means of dialing 911, such as via a cellular
telephone.
